No dumbbell chest workout would be complete without a pull over. For this exercise, you’ll do a drop set, doing a pullover to the point of mid-chest level and then doing a set of pull-overs where you stop just past the head. This is what will help to really activate the upper chest, allowing for that micro focus on the muscle fibers.
Aim for 8-10 reps total of each range of motion, doing two sets and taking 75 seconds of rest between each set.
